A little broader context: This script dispatches jobs into a grid platform. It executes the stub binaries, which execute their grid equivalents and wait until they exit, then returning to my script (where I pick up return codes, parse and process schlock from stdout, etc.)

I actually tried $SIG{CHLD} = 'IGNORE'; first. The net result was that the stub binaries wouldn't submit the grid jobs. I threw up my hands at that. I just don't have grid-fu and the people who were supposed to had no idea why that would occur. (But it was exhaustively demonstrated.)

So I went back to trying to decide between double-fork and setting $SIG{CHLD} to a simple sub that just "wait"s.

(Yes, been back and forth through perlipc before posting here. ;) )
